The objective of this study was to screen the antibacterial and antioxidant activity of thirty nine honey samples from Finland, Sweden, Norway and Denmark. Their physicochemical properties were analysed, antioxidant activity was evaluated by DPPH assay and antibacterial activity against Pseudomonas aeruginosa and Staphylococcus aureus was assessed by microdilution assay. The honey samples obtained were buckwheat, caraway, clover, dandelion, fireweed, heather, lime tree, lingonberry, rape, raspberry, sweet clover, willow, mire, honeydew and polyfloral. Eleven honey samples showed high antioxidant activity. With 15% honey dilution, three unifloral honeys had over 85% inhibition against growth of P. aeruginosa and ten honey samples against S. aureus. The buckwheat, raspberry and honeydew honeys showed the highest antibacterial and antioxidant activity. An unexpectedly high amount of methylglyoxal was found in mire and forest honeys. Some phenolic compounds are shown to be plant species-specific floral markers due to their appearance in specific unifloral honey samples.
本研究旨在筛选来自芬兰、瑞典、挪威和丹麦的 39 种蜂蜜样本的抗菌和抗氧化活性。分析了它们的理化性质，通过 DPPH 法评估抗氧化活性，通过微量稀释法评估对铜绿假单胞菌和金黄色葡萄球菌的抗菌活性。获得的蜂蜜样本包括荞麦、香菜、三叶草、蒲公英、柳兰、石南花、椴树、越橘、油菜、覆盆子、甜三叶草、柳树、沼泽、蜜露和杂花蜜。11 种蜂蜜具有较高的抗氧化活性。在 15%的蜂蜜稀释度下，三种单花蜜对铜绿假单胞菌的抑制率超过 85%，十种蜂蜜对金黄色葡萄球菌的抑制率超过 85%。荞麦、覆盆子和蜜露蜂蜜表现出最高的抗菌和抗氧化活性。在沼泽和森林蜂蜜中发现了出乎意料的高含量的甲基乙二醛。一些酚类化合物由于出现在特定的单花蜜样本中，被证明是植物种特异性的花标记。
